There are behaviors we stopped doing because of speciation. For each of those behaviors, there is a day in history in which one of our ancestors did it for the very last time.

In other words, there's going to have been a moment where the last proto-human to do it hung off a tree branch with their feet for the very last time in the entire evolutionary branch that would eventually become us.
Wild to think about it, I agree.
